Light reflector

Abstract

The light reflector is for use in photography and comprises a cloth 1 raised on radial ribs 2 each of which has a proximal end 3 and a distal end 4. The distal ends 4 of ribs 2 are removably engaged in pockets 5 formed at the angle edges 6 of the cloth 1. Each of the proximal ends of the ribs is removably engaged into a socket 29 pivotally mounted on an armature 10 adapted to be fastened on a lamphead 17. The central portion of cloth 1 is engaged on a sleeve which is part of the armature 10. A locking assembly 36 is mounted on each socket 29 to allow locking thereof in a position where it extends peripherally of the armature 10.

I claim: 
     
       1. A light reflector for use in photography, comprising an armature adapted to be fastened to a light source, a plurality of sockets pivotally mounted to the armature such that each said socket is pivotable between a first position where the socket extends substantially peripherally of the armature and a second position where the socket extends at substantially 90° from the first position, a plurality of radial ribs, each said rib having a proximal end removably engaged in a respective one of said sockets and a distal end spaced from the armature, a metallized cloth supportable on the ribs, the metallized cloth having a substantially central portion which engages said armature and edge portions engaged with the respective distal ends of the ribs. 
     
     
       2. A light reflector according to claim 1, wherein the armature is ring shaped, said first position of the socket being radial to the ring shaped armature and said second position of the socket being substantially parallel to an axis of the ring shaped armature. 
     
     
       3. A light reflector according to claim 2, wherein said ring shaped armature is formed of two rings assembled to one another in facing condition, said facing rings comprising a plurality of radial transverse slots, and each of said sockets being mounted on an arm pivoted between said rings and extending through one of said slots. 
     
     
       4. A light reflector according to claim 3, further comprising a disk mounted between said facing rings, and sleeve means on said disk extending at least partly through said rings for housing said light source. 
     
     
       5. A light reflector according to claim 4, further comprising bayonet slots on said sleeve means for push-and-twist engagement of said light source. 
     
     
       6. A light reflector according to claim 4, wherein said disk is rotatively mounted between said facing rings. 
     
     
       7. A light reflector according to claim 6, further comprising brake means to stop rotation of said disk. 
     
     
       8. A light reflector according to claim 7, wherein said brake means comprise pad means mounted in one of said two rings for reciprocal motion towards and away from said disk, and pusher means on said ring for urging said pad means against said disk. 
     
     
       9. A light reflector according to claim 8, wherein said pusher means comprise bolt means meshing with a nut housed in said ring, said bolt means having one end facing said pad means and another end projecting over said ring. 
     
     
       10. A light reflector according to claim 4, wherein said sleeve means project beyond one of said rings and said central portion of the cloth comprises an aperture engaged on said sleeve means projection. 
     
     
       11. A light reflector according to claim 1, further comprising means for locking the socket in said first position. 
     
     
       12. A light reflector according to claim 11, wherein said means for locking the socket in said first position comprises a sleeve mounted on the socket for reciprocal motion thereon, and a peripheral radial aperture in said ring shaped armature for housing a portion of said sleeve. 
     
     
       13. A light reflector according to claim 12, further comprising spring means between said socket and said sleeve for urging said portion of the sleeve into said radial aperture. 
     
     
       14. A light reflector according to claim 1, wherein the distal end of each of said ribs is removably housed in a pocket formed at said edge portion of the cloth.
